The invention mainly solves the problem of how to meet the requirement of aerial hyperspectral imaging exposure time and reduce image motion at the same time. A hyperspectral camera capable of reducing aerial image motion is characterized in that the hyperspectral camera comprises a laser ranging module and m imaging modules, m is larger than or equal to 2, the imaging wavebands of the imaging modules are the same, the exposure time of each imaging module is set to be 1/m of a standard value, and the standard value is the exposure time needed when a hyperspectral imager is independently used. And the imaging modules are transversely arranged below the aircraft left and right. The method has the advantages that the m imaging modules shoot the same ground area, it is guaranteed that images of the imaging modules are matched with all points on the ground, effective fusion of data between the imaging modules is also guaranteed, and due to the fact that the imaging wavebands of the imaging modules are the same, the exposure time of the imaging modules is equivalent to that the imaging modules can be overlapped, and the imaging efficiency is greatly improved. The exposure time of a single imaging module is reduced to 1/m of the current exposure time, the exposure time is remarkably reduced, and image motion is reduced.

    本发明主要解决的问题是,如何满足航拍高光谱成像曝光时间同时减少像移。一种减少航拍像移的高光谱相机,其特征为,包括激光测距模块、m个成像模块,所述m≥2,所述各成像模块成像的波段相同,各成像模块的曝光时间均设置为标准值的1/m,所述标准值是高光谱成像仪单独使用时所需曝光时间,所述成像模块横向左右排列在飞行器的下方。有益效果是,m个成像模块拍摄的是同一片地面区域,保证了其成像与地面上的各个点是匹配的,也即保证了各个成像模块之间数据的有效融合,并且由于各成像模块成像的波段相同,因此,其曝光时间相当于是可以叠加的,本发明将单个成像模块曝光时间减少到目前的1/m,显著减少了曝光时间,减少了像移。
